TRUCK.

Specification of Letters Patent. Patented Feb, 23, 1915.,

Application filed February 9, 1914. Serial No. 817,421.

T 0 all whom it may concern Be it known that I, HAROLD G. ANTHONY, acitizen of the United States, residing at Chicago, in the county of Cookand State of Illinois, have invented certain new and useful Improvementsin Trucks, of which the following is a specification. I

My invention relates to trucks and has for.its primary object theprovision'of an improved truck which shall have improved means forraising and transportingvarious articles. W

With the above and other objects in View, this invention consistssubstantially in the combination, arrangement, and construction of partsall as hereinafter described, shown in the accompanying drawings, whichform a part of this specification and illustrate the preferredembodiment of my invention, and more particularly set forth in thesubjoined claims.

Figure 1 is a side'elevation'of my improved truck, showing it in itslowered position beneath a desk. Fig. 2 is a side elevation of the truckshown in Fig. 1, illustrat+ ing its raised position. Fig. 3 is a topplan view of the truck shown in Figs. 1 and 2. Fig. 4 is a view inperspective of one of the brackets forming a part of my improved truck.Fig. 5 is a section taken on line 5-5 of Fig. .2. Fig. 6 is a partialsection taken on line 6- -6 of Fig. 2. Fig. 7 is a perspective View of aplatform forming part of my invention and designed to co-act with thetruck in the raising and transporting of articles. Fig. 8 is a sideelevation of the truck illustrated in Figs. 1 to .6 inclusive, incombination with the platform shown in Fig. 7. Fig. 9 is a rear.elevation of the apparatus shown in Fig. 8, with parts broken away. Fig.10 shows a number of the platforms of Fig. 7 illustrated in the positionwhich they occupy when stored.

Reference numeral 10 indicates the lower frame of my improved truck, and11' the upper frame.

Adjacent its forward end the lower frame 10 is provided with an axle 12and wheels approximately vertical upwardly extending 13, as is bestillustrated in Fig. 6. Adjacent its rearward end the lower frame 10 isprovided with swiveled-casters 14, and at its extreme rearwardend theframe 10 bears an steering frame 15.. Upon each side of the steeringframe 15 is secured a hook or stud 16 for engagement with parts to bedescribed.

The frames 10 and 11 are structed of angle bars, as shown in Figs. 4, 5,and 6. Adjacent the rearward end of the frame 10 two pivot plates 17 aresecured, extending upwardly from the frame, and positioned on-oppositesides thereof. These plates are braced by means of a forward cross bar18 and a rearward cross bar 19, these cross bars being approximately inthe same horizontal plane, parallel to each other and at their endsengaging suitable apertures provided in the pivot plates 17. The lowerframe 10 is provided with a forward frame cross bar 20 and a rearwardframe cross bar 21, and the upper frame 11 is similarly provided with aforward frame cross bar 22 and a rearward frame cross bar 23. Twobrackets 24 of equal length connect the lower and upper frames, theirlower ends being respectively pivoted to the forward frame cross bar 20and the rearward frame cross bar 21, while their upper endsarerespectively pivoted to the forward frame crossbar 22 and therearward frame cross bar 23, the two brackets 24 lying in parallelplanes. The upper frame 11, by means of the brackets 24, may be raisedor lowered with respect to the lower frame 11, while remaining at alltimes parallel, thereto. The upper and lower frames are approximately ofequal size, and the lower frame carries four suitably arrangedprojections 26 for limiting the downward movement of the frame 11 andfor supporting it in its lowermost position. cans for raising the upperframe 11 from its lowermost position, illustrated in Fig. 1, to itselevated position, shown in Fig.2, are embodied in the followingdescribed mechanism: A. connecting link is pivoted at its forward endupon the cross bar 23, the mechanism now being described beingduplicated on opposite sides of the truck. A pivot bar 28 is carried bythe rearpreferably conward ends of the connecting links 25 and, I

, its lower end pivoted upon the pivot bar 28,

the lower arm of the handle being slightly longer than the link 27, andthe part of the handle grasped by the operator being relatively long andextending upward from the 5 angle of the handle any suitable distance.The mechanism for raising the upper frame 11 being duplicated onopposite sides of the truck, it is obvious that there are two operatinghandles 29; these handles have their angles joined by a pivot bar 30,which extends from' the angle of one handle to the angle of the otherhandle, and a long rearward link 31 has its lower end pivoted to therearward cross bar 19, and its upper 15 end in pivotal engagement withthe pivot bar 30. As shown in Fig. 2, the rearward end of each of theangle bars forming the sides of the upper frame 11 is notched as at 32for engagement with the pivot bar 28.

Such engagement is had when the upper frame 11 is in itslowermostposition, and

- this engagement assists during the first part of the elevatingoperation, though during the process of elevating the upper frame 11,

the engagement between the pivot bar 28 and the notchedend 32, isbroken. At A is indicated a desk or other object desired to be Hmoved,and which'isspaced from the floor by means of legs a. distancesuflicienttoperftruckj b,eing'in its lowered position.

-mit the truck to bgzi-olled bcneathit, the" In theoperationof'myinvention the truck 2 is; rolle .c nee l flw Object Att ppframe 11 Icing; iniits lowermost position, .oi'ating handles 29 arep'ulled towardthef steering frame 15; This actioniresults in at),adjustment of thevupper framei 11: from ;the lowered: position;illustrated .in'

F ig} 1, to the raised'positionl shown? in Fig, 2, and when the'e'levating processhas been completed, the operating handles' 29 arehooked behind the studs 16, therebylocking the upper framein itselevated position during transportation of the article Assum- 4 ing thetruck to be in the lowered position illustrated in Fig. .l, the abovedescribed- 'pull upon the operating handle will cause the pivot bar 30to act as a fulcrumfor the operating handle, while at the same time it00 oscillates backwardly upon the rearward cross bar 19, the load uponthe upper frame 11 being carried upon the extreme lower end of theoperating handle'and by the connecting link 25, upon which a direct pullis ex- 55. erted. The initialmoving of the upper frame 11 from itslowermost position is assisted by the engagementbetween the pivot bar 28and the notch 32. During the elevating process the brackets 24 and thelinks 27 .60 and 31 oscillate rearwardly about their desired.

A modification of my invention is illustrated in Figs. 7 to 10 inclusivewherein is shown a removable platform B, which forms a part of myinvention and is constructed for coaction with the truck abovedescribed. This platform is provided with legs 33 and is adapted to becentrally posi- 3U tioned longitudinally upon the truck frame 11. Forconvenience in so positioning the platform and truck, the platform isprovided with guide bars 34, preferably constructed of angle bar andoutwardly turned 5 at their ends 35, the guide bars being parallel andproperly spaced to admit of their engagement with the upper frame 11 ofthe truck. Preferably the forward ends of the upper frame 11 are benttoward each other, 0 as at 36 -(see Fig. 3) for cooperation of the truckand the guide bars 34. The height of the platform B is such that theguideways 34 are at a suitable distance from the floor for engagementwith the upper frame to its upper weight carrying surface and'are'provided with casters 37. For the purpose. of. storage theplatforms may be turned upon their sides and rolled into the In the useof the modified form of my invention the object A may be supported andstored upon the platform 13, and when it is desired to move the objectthe truck may be positioned beneath the platform and the platform andobject elevated from the floor, whereupon the operating handles 29 arelocked behind the studs 16 and the platform and object readilytransported.

In the accompanying drawings and in the foregoing description is setforth the preferred embodiment of my invention, but it is obvious thatone skilled in the art may make modifications thereon without departingfrom the spirit of the invention.

I claim:

1. In a truck, the combination of a lower frame having roller contactwith the floor, an upper frame movably joined to and supported by thelower frame, and means for raising and lowering the upper framecomprising an operating handle, two links having their lower ends inspaced relation and pivoted upon the lower frame and their upper ends inspaced relation and pivoted to the operating handle, and a connectinglink pivoted at one end to the upper frame 180 and at the other end tothe point upon the operating handle at which one of said links,

is pivoted.

2.:l'n a truck, the combination of a lower frame having roller contactwith thefloor, an upper frame, means connecting the up per and lowerframes for movement with respect to each other and for maintaining theframes parallel during said movement, and means for raising and loweringthe upper frame with respect to the lower frame comprising a shortforward link and a long, rearward link, the lower ends of said linksbeing spaced from each other, and pivoted to the lower frame, therebeing duplicate links on opposite sides of the truck, an operatinghandle for each side of the truck, a

pivoted bar to the ends of which the lower V ends of the operatinghandles and the upper 20 ends of the short forward links are pivoted,the upper ends of said long rearward links being pivoted to therespectively adjacent operating handles at points equidistant from andabove said pivot bar, and connecting links, one on each side of thetruck, the rearward ends of which are pivoted to the pivot bar and theforward ends of which are pivoted to the upper frame, the rearward endof said upper frame being notched for engagement with said pivot bar.

3. In a truck, the combination of a lower frame having roller contactwith the floor, an upper frame, means movably joining the upper frame tothe lower frame for support thereby and for maintaining the framesparallel during their relative movement, and means for raising andlowering the upper frame comprising a short forward link and I a longrearward link, the lower ends of said links being spaced from each otherand pivoted to the lower frame, said links being duplicated on oppositesides of the truck, an operating handle on each side of the truck, apivot carried by the lower end of each operating handle and to which theupper ends of the adjacent short forward links are pivoted, the upperends of said long rearward links being pivoted to the respectivelyadjacent operating handles in spaced relation to said pivot bar andthereabove, and connecting links, one on each side of the truck, havingtheir forward ends pivoted to the upper frame and their rearward endspivoted to the lower ends of the adjacent operating handles and to theupper ends of the adjacent short forward links, the rearward end of saidupper frame having engagement at each side of the truck with the pivotwhich is common to the connecting link, the short forward link and theoperating handle while the upper frame is in and adjacent to itslowermost position.
